MAGIC TANK Filed Nov. 9, 1929 Patented Mar. 17, I931 not. manner, or min mum, GERMANY MAGIC Application filed November 9, 1929, Serial No.

According to the invention a'vessel made of glass or the like, in which a submersible body such asthat disclosed in U. S. Patent application Serial No. 406,094 rises and sinks, is intended 1 to form a magic apparatus. in that a submersible body repeatedly rises, whereas the sinking of the same is hidden so that it appears, as iilan endless number of bodies rise continua y.

Two embodiments of the invention are illustrated by way of example in the accompanying drawing in which:

Fig. 1 shows in perspective view a magic tank made of glass.

Fig. 2 is a lon 'tudinalsection through the tank compose of two separate tubes.

In Fig. 1 a is a glass tank of rectangular cross section in which the magic arrangement is located. 6 is a vertical glass partition, dividing the tank. into two halves and painted as a background whereby the sinking of the submersible body behind said partition isrendered invisible. This partition 6 is preferably of such height that it extends from the first quarter u to the third quarter of the height of the tanlr. The width of the partition is such that it extends across the entire space between the side walls of the tank a. A glass plate inclined from the rear at the top towards the front at the bottom is situated so that its upper edge is at a. certain distance from the rear walloi the tank. A glass plate (1 inclined from the rear towards the front is provided so that its lower edge is situated at a certain distance from the front wall. of the tank. The inclined partition 0 guides to behind the plate 11 the rising submersible body, not shown in the drawing, which may be of any known construction. The inclined plate (2 on the other TANK 406,095, and in Germany February 29, 1928."

formed of two single tubes 9 it closed at the bottom end, connected with one another by two channels 5 running in'the directions of the plates cand d andwide enough to allow the passage of the submersible body. The painted partition 6 is in this case formed by the walls of the tubes.

1. A magic tank for advertising purposes and as a toy,- comprising in combination with w a submersible body, a tank, a non-transparent vertical partition in said tank, an inclined plate in said tank above said partition adapted to guide said submersible body at the end of its rising movement to'a position behind said partition, and an inclined plate below said partition adapted to guide said submersible body at the end of its sinking movement to a position in front of said partition.

2.-A ma ic tank as specified in claim 1, in which the ower edge of the lower inclined plate is situated at a distance from the front wall of the tank, adapted to form a space for accommodatin the submerged body.

3. A magic tan as specified in claim 1, in which the upper and lower parts of the tank are nontransparent so that a submerged body lying on the bottom is not visible.

In testimony whereof I aflix my signature. 30

hand guides the submersible body in the rising direction to in front of the partition 6. The water level is indicated by e. The tank is not transparent at the portions f so that, as

only the rising of the submersible body is seen, the impression is produced as if an endless number of submersible bodies were rismg. v
